Rose Chart

Version

Application Scenario

·        Rose charts, also known as polar bar charts, are a type of charts that display data using a polar coordinate system.

·        In a rose chart, each data point is placed on a circular plane based on its size and angle.

·        For example, different colors represent different dates, the amount of gross profits maps the radius, and the sales volume maps the angle, as shown in the following figure.

Basic Requirement

The following table shows the basic requirements for a rose chart.

Chart Feature

1. Advantage

·        Intuitive display of directional data: A rose chart can clearly show the directional and periodic characteristics of the data.

·        Visualization of data volumes: The radius can intuitively reflect the data volume.

2. Disadvantage

·        Difficulty in data interpretation: It may be difficult for users who are not familiar with polar coordinate systems to interpret a rose chart.

·        Congestion in data-intensive situations: A rose chart with highly dense data points may appear cluttered, which is difficult to distinguish neighboring data points.
